The reason for the series of posts California and Turkey is that there are man similarities between the San Andreas Fault in California and the fault line cited in the prior article in Turkey. The problem is we haven't had the comparison magnitudes in California that occurred in Turkey.
California is over due for some major 6.5 or greater qaukes along the San Andreas Fault. Now the now the posts concerning YUCAIPA are related because of the side or near tension movement from one area to the other. This was cited as part of the Turkey article. The recent Hector Earthquake is setting up for three conversations to continue.
Yucaipa, Long Valley Caldera, and the Salton Sea Areas. The area of greatest stress is the area know as the Mojave Block (see http below for a complete glossary of Earthquake terminology and the Mojave Block)or 2 degrees around Yucaipa, California.
